Surprise Pitcher Earns Red Sox Call-Up
22 Apr
Summary
- Eduardo Rivera promoted to majors quickly after minor league success.
- Rivera was signed by Red Sox after release by Oakland Athletics.
- He will be fifth pitcher to debut for Boston this season.

Boston Red Sox prospect Eduardo Rivera has unofficially joined the major league team, receiving a call-up on Tuesday night following his recent promotion to Triple-A Worcester. This move comes as the Red Sox have frequently needed to utilize their pitching depth early in the season.
Rivera's rapid progression is notable, especially considering he was an international free agent signed by the Oakland Athletics. After his release mid-season in 2024, the Red Sox signed him, and he has since impressed with strong ERA numbers in the minors.
The 22-year-old has shown versatility, performing well as both a starter and a reliever. He recently struck out 16 batters in 10 innings with a 2.45 ERA for Portland. His addition to the active roster will likely involve optioning another pitcher, with a spot on the 40-man roster needing to be cleared.
This call-up makes Rivera the fifth pitcher to potentially debut for the Red Sox this season, underscoring the team's ongoing need for pitching reinforcements. The team has options for clearing roster space, including placing players on the injured list.
